pulse width.

The two-level turn-off sequence can be disabled by connecting the LVOFF pin to VH and

connecting the CD pin to VREF with a 4.7 k

Ω resistor.

is slightly reduced and the total output width can be smaller than the input width (see

Figure 7).

Output stage

The output stage is able to sink/source 1.7 A/1.3 A (typical) at 25 °C and 1.0 A/0.75 A min.

over the full temperature range. This current capability is specified near the usual IGBT

Miller plateau.

Undervoltage protection

Undervoltage detection protects the application in the event of a low VH supply voltage

(during startup or a fault situation). During undervoltage, the OUT pin is driven low (active

pull-down for VH>2V, and passive pull-down for VH<2V).
